DIFFERENTIAL GEARBOX ASSEMBLY FOR A TURBINE ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17806574 titled 'DIFFERENTIAL GEARBOX ASSEMBLY FOR A TURBINE ENGINE

Simplified Explanation

The abstract describes a differential gearbox assembly for a turbine engine that connects the fan shaft and the drive shaft. It includes an epicyclic gear assembly with a sun gear, planet gear, and ring gear. The sun gear is connected to the drive shaft, while the planet carrier is connected to the fan shaft. The assembly also includes an electric machine assembly that provides mechanical power to the fan shaft through the epicyclic gear assembly.

  • The differential gearbox assembly connects the fan shaft and the drive shaft of a turbine engine.
  • It includes an epicyclic gear assembly with a sun gear, planet gear, and ring gear.
  • The sun gear is connected to the drive shaft, while the planet carrier is connected to the fan shaft.
  • The assembly also includes an electric machine assembly that provides mechanical power to the fan shaft through the epicyclic gear assembly.

Potential Applications

  • This technology can be used in turbine engines for various applications such as aircraft propulsion systems, power generation, and industrial machinery.

Problems Solved

  • The differential gearbox assembly solves the problem of efficiently transferring power from the drive shaft to the fan shaft in a turbine engine.
  • It provides a compact and reliable solution for connecting the two shafts and allows for power transmission through the epicyclic gear assembly.

Benefits

  • The use of the epicyclic gear assembly allows for efficient power transmission between the fan shaft and the drive shaft.
  • The electric machine assembly provides additional mechanical power to the fan shaft, enhancing the overall performance of the turbine engine.
  • The compact design of the differential gearbox assembly saves space and allows for easy integration into turbine engine systems.


Original Abstract Submitted

A differential gearbox assembly for a turbine engine having a fan shaft and a drive shaft. The differential gearbox assembly includes an epicyclic gear assembly coupling the fan shaft to the drive shaft. The epicyclic gear assembly includes a sun gear, a planet gear constrained by a planet carrier, and a ring gear. The sun gear is coupled to the drive shaft and the planet carrier is coupled to the fan shaft. The sun gear, the planet gear, and the ring gear all rotate about the drive shaft. The differential gearbox assembly includes an electric machine assembly that includes an input coupled to the epicyclic gear assembly. The electric machine assembly provides mechanical power to the fan shaft through the epicyclic gear assembly.
